NPs were characterized using standard techniques. PXRD confirmed a highly crystalline cubic phase with a crystallite size of 33–34 nm, while SEM revealed an agglomerated plate-like morphology FTIR confirmed Ba–O and Bi–O bonds at 695 cm⁻¹ and 351 cm⁻¹. UV–Vis analysis showed peaks at 256 nm, 307 nm, and 399 nm, with a band gap of 3.08 eV. The shielding properties were evaluated, revealing strong gamma-ray attenuation and high neutron absorption efficiency, surpassing traditional materials like lead, concrete, and steel. Radiation shielding studies demonstrated a mass attenuation coefficient of 0.394 cm²/g at 0.276 MeV and a Tenth Value Layer (TVL) of 0.302 cm. Neutron shielding efficiency was confirmed by a scattering cross-section of 7.40 barns and an absorption cross-section of 0.034 barns. Ba

exhibits excellent shielding efficiency, making it a promising candidate for radiation shielding in medical and industrial environments, with the added benefit of reduced toxicity.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
